Comments let you talk about an email thread inside Slashy without forwarding it. Threads stay clean, replies stay private, and @-mentions notify the right person.

​
Adding a comment

Open a thread and click the comment icon in the thread header, or press c. A side panel opens with a comment composer. Type your message and submit with Cmd+Enter. The comment appears in the panel alongside the thread, timestamped and attributed to you.

Who can see a comment

Comments are private to people on your team who already have access to the thread. That means:
  • Teammates you’ve @-mentioned on the thread.
  • Teammates who share the inbox via Slashy’s shared-inbox setup.
People on the email itself (external recipients, the sender, anyone in To or Cc) cannot see comments. Comments never appear in the email body, never get sent, and never leak through reply-all.
Sharing an inbox with a teammate gives them access to existing comments on threads in that inbox. If you have sensitive comments, review who has shared access in Settings → Inboxes before enabling sharing.

​
@-mentioning a teammate

Type @ in the comment composer to open the mention picker. Slashy suggests teammates from your workspace. Pick one and the mention is inserted; they get a notification.

If a teammate isn’t in the picker, they haven’t joined the Slashy workspace yet. Invite them from Settings → Team.

​
Notification behavior

When you’re @-mentioned:
  • You get a notification through every channel you’ve enabled for the Comments category (desktop, browser push, mobile, email digest).
  • The thread shows up in your “Mentions” view, accessible from the left sidebar.
  • The comment is highlighted with a yellow accent the first time you open it.
If a teammate adds a comment to a thread you’ve previously commented on but doesn’t @-mention you, you do not get a push notification by default. You can opt into “All comments on threads I’ve commented” in Settings → Notifications → Comments if you want that.

​
Editing and removing comments

Hover a comment you posted to reveal the edit and delete actions. Editing keeps the timestamp; deleting removes the comment for everyone who can see it. Slashy does not show “(edited)” markers on comments. You can only edit or delete your own comments. To remove someone else’s comment, ask them, or remove their access to the shared inbox.

​
Mobile

Comments are visible and postable from the iOS app’s thread view. The composer behaves the same way as desktop, including @ to open the mention picker. Long-press a comment to reveal edit and delete actions.
